This invention relates to clamps adapted for use in coupling a plurality of closely arranged drums to maintain the drums in assembled relationship to each other against relative shifting when stored on any conveyance of transportation, such as ships, freight-cars, trucks and the like. More particularly, the invention deals with a clamp formed from a single clamp member which can be used in pair or multiple pairs, the clamps having means to couple adjacent pairs together in predetermined uses thereof.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts 2 Claims. (01. 24 s1') are designated by suitable reference characters in'each of the Views and, in which: r

Fig. 1 is .a diagrammatic edge view of parts of two drums, indicating ring portions of the drums and showing a clamp arranged thereon, wherein two pairs of clamps are coupled together.

Fig. 2 is a section on the line 2-2 of Fig. 1 indicating parts of the drums in elevation.

Fig. 3 is a section on the line 3-3 of Fig. 1 with parts of the construction broken away; and

Fig. 4 is a partial section on the line 44 of Fig. 1 omitting part of the construction.

My present invention deals with clamps of the general type and kind disclosed in my prior application, Serial Number 86,569, filed April 1949, and, more particularly, my invention deals with a clamp structure, wherein two or more identical clamp members can be assembled to form what may be termed single or double clamps.

In the drawing, I have indicated at 10 and. H, portions of two drumshavin circumferential rings on the periphery thereof, as at [2 and I3 respectively, the rings being of I,-beam crosssectional form, as more clearly seen in Fig. 2 of the drawing. These rings are welded or otherwise secured to the periphery of the drums and are usually disposed at spaced intervals on the drum, but only one set of the rings are illustrated in the accompanying drawing.

The rings I2 and I3 have upwardly and downwardly extending flanges I2, I3 which are adapted to be engaged by the clamp, generally identified by the reference character 14. In illustrating one use of the invention, I have shown the clamp I4 composed of two pairs of clamp members, one pair being generally identified by the reference character l5 and the other pair by the reference character 16 in Fig. 1 of of the drawing.

the drawing. As each clamp member employed in each pair is of'the same construction, the brief description of one will apply to all. However, in considering Fig. 4 of the drawing, the separate clamp members are identified by the reference characters [5, l5" and by Hi and I6" so that, for purposes of description, the clamp members [5, Hi can be regarded as the upper and the members I5 and I6" can be regarded as the lower.

.Eiachclamp member is generally of a more or less triangular formation having a straight wide outer edge'portion l-T, curved side edge portions as at 18 and, a narrow flat inner edge portion l9; The upper surface 20 of the clamp is generally fiat except for a raised bearing portion 2| at the narrow end IS, the raised bearing portion bein apertured, as indicated at 22 for the reception of a coupling pin 23. The outer wide end portion ll of the clamp member has a vertical aperture arranged centrally with respect to, said edge portion, as seen at 24, and this aperture is adapted to receive a clamp bolt 25.

Considering Fig. 4 of the drawing, it will appear that the inner or lower surface of the clamp plate adjacent the end portion I! thereof and in the region of the aperture 24 has an enlarged body portion 26, the inner or lower surface 21 of which is adapted to come into close proximity with the corresponding surface on the companion member l5" of the pair of clamp members,'o'r plates. The inner surface of the member 15 has curved grooves or recesses 28 and 28' which open outwardly through the flat contracted end l9, as seen at 28" in Fig. 3 of the drawing and, otherwise, are parallel to the curved edge portions l8 and these grooves are adapted to receive the flanges l2, 13', as clearly seen in Figs. 2 and 3 Sufiicient clearance will be allowed in the grooves to freely receive the flanges.

outwardly of the grooves 28, 28, the surfaces 29, 29' of the member l5 are raised sufliciently to compensate for the thickness of the ring, but

to enable the plate to have a clamp engagement upon the ring along these surfaces. Other inner surfaces of theplate are recessed, asygenerally indicated by th reference character 30 to lighten the weight of the plate member as much as possible.

In the above description, the references have been applied primarily to the plate member I5". However, as all of the other plate members, namely l5", l6 and I6" are of the same, construction, like references will designate like I on these other plate members, thus the reference character 2| is applied to the projecting apertured bearing portion of the plate member IS in Fig. 1 and to the corresponding member 2| of the member is formed by dies, whether it be by stamp ing, forging or casting and two or four of these plate members can be assembled to produce'a'half or a double clamp, which ever is desired to be used in a given assemblage.

or necessary, the other pair l6, Hi" can also be employedand pinnedtogether by the coupling pins 23; In the latter .use, it will be apparent that the plate members I 5', I 6" can be first coupled together, as alsothe plate members l5" and I6 and then the two members so joined or coupled together by the bolts 25;

Having fully described my invention, what I claim-Jae new and desire too-secure by Letters Patentis:

1. A clamp device for use in securing'drums having=rings on the peripheral surfaces thereof in retaining adjacent'drums against displacement; said clamp comprising two pairs of substantiallyzV-shaped plates of the same general size and contour,v said plates having registering grooves on adjacent surfaces thereof diverging from one narrow endof the plate to the other Wide end thereof, the last named end portion of each plate being apertured to receive a clamp bolt, said plate adjacent the bolt being of greater thicknessthanat side edges of the plate beyond the limits of said grooves, said grooves converging at the narrow end'of the plate, said narrow end" In other-words, the plate members #5, I5" alonecould be-usedasa; pair to clamp adjacent drums together but, where added strength and rigidity is deemed advisable portion of the plate having an outwardly pro-1 jecting apertured member, said apertured member extending beyond said end portion of the plate to register the aperture of the member of one plate with the aperture of the member of a companion plate in a pair, and a coupling pin passed through said registered apertures in securing the plates together.

2. A clamp of the class described, comprising two pairs ofsubstantially similar triangular plate like members, each member having a narrow end 7 and a wide end, grooves opening through one surface of said member paralleling side edges of said ,member, said grooves converging at the narrow end of said member, the Wide end portion of said member being fashioned centrally thereof to receive clamping mean for clamping saidpairs of said members together for engagement with a support arranged therebetween, the thickness of said member adjacent said last-named means being 'greaterthan the-thickness of the member at'the sideedge-portions thereof, an apertured' portion projecting outwardly and beyond the narrow end portion of'saidmember and adapted'to register'with anapertured portion of a companion member of a pair, and means coupling saidapertured portions in uniting each pair of members.
